My invention relates to ,iinpactcmembers such as automobilebumpers, and the like,

One object o-f my invention is to provide,

in combination with a bumper barstructure that is attached to a motor vehicle by fitting may-take are shown in the acconipanying I drawing, wherein 'Figure 1 is a front elevationalvlew of one'form "of bumper structure; Fig; 2- is a View, taken 'onthe line 22 of Fig. 1;; Fig. 3 is a 'VlBW taken on the line 3fl3 of Fig.1; Fig. 4 is afront elevational view of a modified'form of bumper structure, and Fig. is a view,.partially in plan and partially in section, showing another-modification, v .The impact-receiving portion of the apparatus-comprises two flexible bars .6, preferably of steel, that have eye-portions in 4 their outer ends through which tiebolts 7 extend, to-hold them inassembled relation. Intermediate or tie bars 8, preferably also of spring steel, have eye-portions in their outer ends,"through which the bolts 7 extend. These bars 8 extend toward the mid portionsotthe bars 6' and are provided with a series of holes. a Face plates 9 that may serve as name plates areclamped against the frontfaces of the bars 6 and 8'. bybolt's 1O that extend through such plates and the holes in the bars 8, and througha back plate. llgas shownmore clearly in-Fig. 3. A palr of angle plates 12 are riveted to each ofthe backplates 11 and are providedwith per.-

forations through which a bolt 13 extends.

Bracket-arms 14, the rear ends of which are secured to an automobile (not shown) in any suitable usual manner, have eye-portions that surround the bolts 13. so that a pivoted joint is formed between each bracket arm 14 and a pair of angle irons 12.

'I'he intermediate bars 8 thus securely hold the face plates 9 in longitudinally rigid relation to the impact bars 6, thus preserving the symmetrical arrangementot the plates 9, and also maintaining the, bumper bars 6.

in symmetrical position with respect to the sti iifetiiie Y bracket '44, and hence symmetrical. with resistant to impacts,

.respect .to the vehicleto' gwliich thebracket arms are attached. The intermediatebars I more -often subjected to impacts than are the mid portions of thebars, "but areqlress further exert, a stiffening eflect upon. the I v outer ends of thebarso which are not only I lat 8 in.Fig. 5, so that while suchbarsiwill still serv-cfa s sufficiently rigid tie :members for the face plates 9 and their associatedthe. wide 'tacesat the ends of the bars as having a. cumbersome or weightyfappear ance. The structure of Fig. 5, will',1in other fittings, they will, nevertheless, beless con-' Y spicuous, because some users may object. to-

respects, be substantially the'same as shown in Figs. 1 to-3 ..L v e Referring; now to. Fig; 4, I show impact bars 6* that are of the sameform as-gthe bars 6. In this arrangement, the bars 8a1e eliminated and a single bar 15, at the mid portion of the bars 6 is substitutedtherefor. Thebars 16 are held in assembled relation by tiebolts 7, and spacer rings 16" are provided around the bolts 7? and between the bars6 .The intermediate bar 15 is connect ed to face plates 17 bybolts l8ythatex tend therethrough and through holes in the ends of the. bar 15. Fittings corresponding a, E l

to the membersllQlQ. 13 and 14 ofjFigs.

1 to 3.wil1' be provided for the bars 6 .The variousholes in'th-eends .ofthe bars- 8 If: and 15are .providedfor the purpose of permitting adjustment to vehicles of various widths, since by changing the positions of" the bolts 10 and 18 longitudinally of the intermediate bars, the arms 14 canbe moved f further apart and brought closer together, as

desired. Or stated in other words, with the arms 14 attached to a vehicle, the various holes permit convenient attachment of the arms to the impact bars,fat desired points longitudinally thereof.

- It will be understood thatother forms of bers 1'1, 12, 13, etc., and that the intermediate or tie bars may be of'various other forms. For instance, the tie bar 15 may be deflected rearwardly at its mid portions 10o v fittings may be providedinstead of the a I claim as my invention:

1. Bumper structure, comprising a pair of vertically spaced parallel bars, plates at each side of the mid portion thereof, means for securing the plates to said bars and to a bumper support, and tie bars secured to said plates and the extremities of said bars, the

, tie bars being disposed in parallelism with the first named bars. v

2. Bumper structure, comprising a pair'of vertically spaced parallel bars, plates at each side of the mid portion thereof, means for securing theyplates to said bars and to a bumper-support, and tie bars secured to said plates and the extremities of said bars, the

tie bars being disposed between and in parallelism with the first named bars.

3. Bumper structure, comprising a pair of vertically spaced parallel bars,plates at each side of the mid portions of said bars, means for securing the, plates to said bars and to a bumper support, and means disposed entirely between said bars for rigidly holding said plates in predetermined relative positions. 7

tween the first named bars, and having eye portions in the outer ends thereof, and each connected at its inner end to one of the said plates, and tiebolts extending through ad jacent eyeportions ofthe variousbars.

, 6. Bumper structure, comprising an. impact-receiving bar, an attaching plate 'between the mid portion and each ,endthereot, tiebars connected at their outer ends to said bar, and means for connecting each of said plates to the inner end of one of said tie bars, at various points longitudinally thereof.

7QBumper structure, comprising an impact-receiving bar, an attaching plate .bc-

tween the mid portion and each end thereof, tie bars connected at their outer ends to said bar, and means for connecting each of said plates to the inner end of one of said tie bars at various points longitudinally thereof, said means comprising a plurality ofiongitudi nally spaced holes in the tie bars and bolts extending through the plates and holes in said tie bars.

8. Bumper structure, comprising an impact-receiving bar, an attaching plate connected to said bar intermediate the ends thereof, a tie bar extending in the same general direction as the first named bar, means adjustable in a direction longitudinally of said bars, for connecting one end of the tie bar to said plate, and means forconnecting the other end of said tie bar to the first named bar. 7 r

9. The combination with a pair of bumper supporting arms, of a pair of verticallyspaced parallel bars, a plate at each'side of the mid portion of the bars, means for securing the plates to said'bars, means lfor securing the plates to said supporting arms, and tie bars having interlocking connections with said plates and to the ends of said par allel bars.

10. They combination with" a pair of bumper supporting arms, of a pair otvertt cally-spaced parallel bars, a plate at'each side ofthe mid portion of the bars, means for securing the plates to said bars, "means for securing the plates to sa1d' support1ng arms, a tension member, and interlocking connections between said memberand each otsaid-plates and the parallel bars, for holding said plates in predetermined relative positions. 3

11. The combination 'with a pairoi bumper supportingarms, of a pair of Vertically? spaced parallel bars, a pair of clamping plates at each side of the midportion of the said bars, means for'clamping the plates to said bars, means for securing the plates'to the supporting arms, and atension device interlocked with each pair of plates and the said parallel bars, for holding-said plates in predetermined relative positions.

'In testimony whereof, I, the said F ED ERICK G. BREMER, have hereunto" set" my hand.
